K3 Headphones

Doug Turnbull
Sam,

    When this topic was previously discussed I saw mention of Extreme
Isolation EX 29 headphones which provide:

1) Good noise suppression (29 dB or nearly a factor of 1000 at 1000 Hz) so
you can keep the volume down and not hear your station's fans or the TV in
the next room.

2) Comfort and an adjustable padded headband.

3) Exact impedance match for the K3 at 32 Ohms and hence plenty of volume
from the K3.

4) They are California made and cost $99.

5) Stereo headphones with built in adapter for the larger phone plug jack
used on the K3 front panel.   The adapter plugs in and then screws home over
the smaller stereo plug attached permanently to the phones.   The plugs
appear to have gold plating, which is a complete waste.
6) They come with a nine foot line cord which I just wrapped around a
toroidal core even though I was not experiencing problems with noise.   They
are also available with a 40 inch long cord.

I purchased a set and am most pleased with them.

 

 

     You can look the Extreme Isolation EX-29 Headphones up on Google or go
to http://www.quietheadphones.com/product/ex-29 and order by post for $99.
These headphones are made for musicians to use in groups but I think they
are missing another market.

 

     I also have the Heil Proset Plus but prefer these cans for CW work.
Both sets of phones have their advantages but for CW the Extreme Isolation
phones are more to my liking.   The EX 29 will be clamped to my ears this
weekend for CQ WPX.

PS EI5DI wrote an article for the NCJ some time back on the subject of
headphones.   He prefers Sony MDR EX71SL ear buds because cans bother his
ears when he is wearing glasses.   I also wear spectacles but mine have a
thin wire frames and are comfortable with headphones.

Re: K3 Headphones

I've had Sennheiser HD400 for many years (long since out of production
but there is a newer model). These are very light. I've also the Heil
Proset noise cancellers. The Proset and any other can-style headphone
I've ever used just kill my ears after a while, like in a contest. The
HD400's are better but still, eventually after 4 hours or so I have to
take them off.

I bought a set of Sennheiser CX300-II earbuds on ebay new for $35, some
special. I think they're regularly $50. These have excellent sound
quality as one expects from Sennheiser. They're noise blocking, nearly
as good as the Heil noise cancellers. And they completely solve the long
term ear pain issue. I can wear them all day (or night) without any
discomfort.

I set the K3 AF Gain to Low and the AF LIM to 20.

Highly recommended!
